Abstract
A system and methods for location authentication are presented. A subset of demodulated server received navigation signals are selected synchronized to client bit frames to provide synchronized server bit frames. A function of the synchronized server bit frames is computed to provide a server signature set. A client signature set and the server signature set are compared to provide a comparison result, and a location of a client device is authenticated based on the comparison result.
